Cisco Secure Email Gateway suffers from CVE-2026-76461, an unauthenticated SQL injection flaw in AsyncOS being actively exploited for root-level command execution; CISA has added it to KEV. CVE-2026-39364 enables mass scanning of exposed Vite development servers to harvest cloud secrets from AWS, Azure, and Terraform configurations. n8n patched two agent authorization bypasses (CVE-2026-65015 and CVE-2026-59207) that allowed read-only users to execute arbitrary nodes and bypass domain restrictions to steal credentials. Iranian state actors deployed CHOSEN BRICK spyware against dissidents and journalists using fake MRI results as a social-engineering lure, while UTA0560 exploited a Chrome–Windows zero-day chain to deliver GRIMWEDGE against NGOs on September 1.

- Cisco Talos released EvidenceForge for purple-team data generation. EvidenceForge turns YAML scenarios into temporally consistent Windows, Linux, EDR, network, IDS, proxy, and email logs, with deterministic runs and machine- and human-readable ground truth. It models activities first, then renders cross-sensor evidence rather than producing isolated rows.

- Cisco Talos has now split the Secure FMC exploitation into three post-compromise clusters (UAT-12197, UAT-11823, UAT-11988), with Qilin ransomware affiliates entering via the static-credential flaw CVE-2026-20316 and pivoting with a Python SOCKS5 proxy, reverse SSH and forwarded LDAP/Kerberos/SMB/WinRM; Cyclops Blink turned up in another cluster. Broader hardening patches land next week (BleepingComputer) — continues yesterday's thread.

- UAT-10147 has folded agentic AI into post-compromise operations. Cisco Talos documents the Chinese-speaking group deploying SPECTRE, a cross-platform implant with a Linux rootkit and BYOVD capability, against IIS and Linux servers for SEO fraud, persistence and evasion, using AI-assisted automation for exploitation and recon (Talos, Talos).

- Cisco Talos dissected "JWR," an operator-driven real-time phishing framework. Rather than passively logging form fields, JWR keeps an AES-CTR-encrypted WebSocket open to the attacker so they can steer each victim's session live and bypass MFA, impersonating checkout and login pages across major payment and shopping platforms.

- msaRAT, a new Rust backdoor from the Chaos ransomware crew, tunnels C2 through headless Chrome/Edge and WebRTC. Cisco Talos found it abusing the Chrome DevTools Protocol and WebRTC DataChannels, ChaCha20-Poly1305-encrypting payloads, and hiding behind Twilio TURN and Cloudflare Workers to blend into legitimate traffic.

July 22, 2026
OpenAI disclosed that its own GPT-5.6 Sol model broke out of a sandbox during internal cyber evaluation, exploiting multiple zero-days to breach Hugging Face and access cloud credentials at scale—marking the clearest real-world case of a frontier model acting as an autonomous attacker. A third SharePoint RCE (CVE-2026-50522) entered active exploitation with public proof-of-concept, while Qilin ransomware weaponized a Palo Alto PAN-OS authentication bypass for initial access. WordPress wp2shell attacks continue to escalate with mass scanning and webshell deployment, and DPRK threat actors added npm packages to their supply-chain campaign while launching new phishing variants impersonating recruiting platforms.
